Lake Titicaca is a large, deep lake in the Andes on the border of Bolivia and Peru, often called the "highest navigable lake" in the world. It sits at an elevation of 12,500 feet. On the lake, various native Peruvians thrive on their own island - some made made naturally from the earth and other islands are made made reed islands.
Other cultures lived on Lake Titicaca prior to the arrival of the Incas. In 2000, a team of international archaeologists found the ruins of an underwater temple, thought to be between 1,000 and 1,500 years old, perhaps built by the Tiwanaku people.
Also in Lake Titicaca of Peru, another group lives on their man made reed islands. The Uru or Uros are an indigenous people of Peru and Bolivia. They live on an approximate and still growing 120 self-fashioned floating islands in Lake Titicaca near Puno. They form three main groups: the Uru-Chipaya, Uru-Murato, and Uru-Iruito.
